Important Safety Information
Methyl Ethyl Ketone Peroxide (MEKP)
MEKP is among the more hazardous materials
found in commercial channels. Proper handling
of the “unstable (reactive)” chemicals presents a
definite challenge to the plastics industry. The
highly reactive property which makes MEKP
valuable to the plastics industry in producing the
curing reaction of polyester resins and gel-coats
also produces the hazards which require great care
and caution in its storage, transportation, handling,
processing and disposal.
Workers must be thoroughly informed of the hazards
that may result from improper handling of MEKP,
especially in regards to contamination and heat.
They must be thoroughly instructed regarding the
proper action to be taken in the storage, use and
disposal of MEKP and other hazardous materials
used in the laminating operation.
MEKP is flammable and potentially explosive,
as well as potentially damaging to the eyes and
skin.
Read material manufacturer’s warnings and
material MSDS to know specific hazards and
precautions related to MEKP.
Contaminated MEKP can become explosive.
Prevent contamination of MEKP with other materials, which includes, but is not limited to polyester
overspray, polymerization accelerators and promoters, and non-stainless metals. Even small amounts
of contaminates can make MEKP explosive. This reaction may start slowly, and gradually build-up heat,
which can accelerate until fire or an explosion result.
This process can take from seconds to days.
Heat applied to MEKP, or heat build-up from contamination reactions can cause it to reach what is
called its Self-Accelerating Decompisition Temperature (SADT), which can cause fire or explosion.
Spills should be promptly removed, so no residues
remain. Spillage can heat up to the point of selfignition. Dispose in accordance with manufacture’s
recommendation.
Store MEKP in a cool, dry and well-ventilated area
in the original containers away from direct sunlight
and away from other chemicals. It is strongly recommended that the storage temperature remain below
86° F (30° C). Heat will increase the potential for explosive decomposition. Refer to NFPA 432.
Keep MEKP away from heat, sparks and open
flames.
GC-1393F
Current catalysts are premixed and do not require
any diluents. GlasCraft strongly recommends that diluents not be used. Diluants add to the possibility of contaminates entering the catalyst system. Never dilute
MEKP with acetone or any solvent since this can produce an extremely shock-sensitive compound which
can explode.
Use only original equipment or equivalent parts
from GlasCraft in the catalyst system (i.e.: hoses, fittings, etc.)

Pressure Relief Procedure
4. Verify the trigger lock is engaged.
To relieve fluid and air pressures:
1. Push down Yellow slide valve, P/N 21402-00 to bleed
off air to system.
Daily Maintenance
It is recommended that the following service be performed on a daily basis.
2. Open P/N 21228-00 on catalyst pump to recirculation
position.
1. Remove gear cover, p/n: 23789-00, and inspect valves
to see if there is any leakage, on the top or bottom
side of the valves. if there is leakage, with pressure
relieved, tighten packing nut, p/n: 23764-00 1/8 to 1/4
turn until leak stops. Verify that there is no leakage.
3. Open P/N 21192-00 on bottom of material pump.
4. Maintain a reasonable stock level of “wear” items
such as Packings, Seals and O-Rings
5. If dispense gun is leak tested, be sure to dry gun
thoroughly.
6. Never leave dispense gun immersed in any liquid.

Maintenance
Parts Replacement Procedure
Formula Gun
Before performing maintenance on the dispense gun,
follow Pressure Relief Procedure.
Notice
Due to the different o-ring materials and lubricants used
in the dispense guns, never submerge or soak any dispense gun in any type of solvent. Submerging or soaking any dispense gun will immediately void the gun warranty.
1. Read each procedure entirely before beginning
and refer to the illustration views as needed.
2. Flush and clean all passages as they become
accessible.
3. Clean all parts before assembly.
4. Replace all O-Rings, Valves and Seals with new
parts from the appropriate kit.
5. Inspect all parts for wear or damage and replace
as required with new GENUINE GlasCraft
REPLACEMENT PARTS from your authorized
GlasCraft Distributor.
6. Inspect all threads for wear or damage and
replace as required.
7. Tighten all threaded parts securely, but not
excessively, upon assembly.
8. O-rings can fail if subjected to any of the
following conditions.
a. Swelling - coming in contact with
solvent or oil from compressor.
b. Cut - sharp, unlubricated edge in gun
head or handle.
c. Sticky - contaminated with oil, water,
solvent, catalyst, resin or gel-coat.
d. Chaffing - dry sliding surfaces (needs
lubrication).
